GENERAL HISTOLOGY

Detailed explanation-1: -By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center. DNA replication, transcription, and RNA processing all take place within the nucleus, with only the final stage of gene expression (translation) localized to the cytoplasm.

Detailed explanation-2: -Nucleus is known as the control center of the cell as it performs the following functions: The nucleus contains the hereditary material of the cell, the DNA. It sends signals to the cells to grow, mature, divide and die. The nucleus is surrounded by the nuclear envelope that separates the DNA from the rest of the cell.

Detailed explanation-3: -The nucleus has 2 primary functions: It is responsible for storing the cell’s hereditary material or the DNA. It is responsible for coordinating many of the important cellular activities such as protein synthesis, cell division, growth and a host of other important functions.

Detailed explanation-4: -Definition. A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. An array of holes, or pores, in the nuclear membrane allows for the selective passage of certain molecules (such as proteins and nucleic acids) into and out of the nucleus.

Detailed explanation-5: -The nucleus is a small, round and membrane-bound structure found in cells. And the fluid inside the nucleus surrounded by the nuclear membrane is called nucleoplasm. It controls cell’s growth and reproduction as it contains cell’s hereditary information. It’s covered by dual layer called a nuclear membrane.
